Development of state reference samples of mercaptan sulfur content in petroleum products

In recent years, there has been a further development of refining technology, which make it possible to better use of crude oil, which also has a major impact on the quality of bitumen. Most European refineries, of course, are processing, for reasons of the resale of petroleum products, especially petroleums suitable for the recovery of light and middle fractions. Therefore, light petroleums are required, with low yields of heavy fractions, which are highly economically and in dispositions efficient for processors on the petroleum market. Emphasis is placed on the sulfur content, the paraffin content is no longer the most important aspect. Less important from the perspective of the refinery is the content and the ratio of asphaltenes and maltenes. There is no doubt that we will have to change our view on petroleum products. Their availability will continue to decline, their price, on the other hand, is likely to grow in relation to falling supplies of resources. Therefore, the view of the bitumen must be changed. The most common way of production of PG bitumen is vacuum distillation, which is carried out in such a way that the vacuum distillation residue satisfies it´s properties bitumen requirements for the relevant penetration.

The feasibility of utilizing petroleum coke as an alternative fuel for cement kilns and other industries was suggesting. The feedstock using in this study are mixture (T-21A+T-5) Tawke and Shekhan PF2 AT residues were obtained from two Iraqi-Kurdistan crude oils by removing distillates boiling point up to 350°C using the atmospheric distillation unit. The coking processing of AT residues at high temperatures to produce gas, coking distillates and petroleum coke. Coking of AT residues were carried out at temperature 450-460°C and atmospheric pressure, at this temperature, the duration of heat treatment of the feed was 2h. 45 min for Tawke and 2h. 15 min for Shekhan. The choice of temperature and time of the experiments was made on the basis that a lower temperature increases the duration of the process, and at a higher temperature a significant reduction in the duration of the process according to GOST methods, it becomes difficult to obtain the target product with the required content of volatile substances. An increase in the duration of the coking process about 3 hours and more in all cases leads to a decrease in the content of volatile substances. The study was suggested petroleum coke can be using instead of fuel oil on industry effectiveness in cost reduction when switched over from fuel oil to petroleum coke. in the last of this work, after all the measurements and characteristic obtained, two types of treatment scheme were proposed for how to refine these types of crude oils, which give petroleum products with a high sulfur content. The research proposed the technological, ecological and economic aspects of petroleum coke as fuel, including high sulfur content, use as energy in the electrical field (electro energy), and as an alternative fuel for cement production and metallurgical manufacture.
